High-performance multiple blend polymer solar cells (PSCs) were firstly achieved via a multiple cascade energy level engineering strategy. By introducing more different bandgap copolymers with the similar molecular backbones, steadier energy level alignment and more charge transfer channels in devices could be realized.
